In a new map posted by the Equal Justice Initiative, the south glows red.

The brightness of the red indicating how many lynchings have been reported in each county.

The further north and west show a smattering of dark red shaded counties.

And in Michigan, there is just one — St. Clair County.

The map is part of the initiative's efforts to face and reflect on the country's history of lynching and racial terror. It also recently opened a new memorial in Montgomery, Alabama.

"The Memorial for Peace and Justice was conceived with the hope of creating a sober, meaningful site where people can gather and reflect on America’s history of racial inequality," its website reads.

The site includes more than 800 steel columns the county and name of each lynching victim engraved on the columns.

There has been one reported lynching in Port Huron.

In the early morning hours of May 27, 1889, a mob of men stormed the county jail looking for 23-year-old Albert Martin.

The bi-racial man had been charged with allegedly assaulting a farmer's wife May 11.

In the 4 p.m. edition of the May 27, 1889, Times Herald, staff reported that rumors of a lynching had circulated and police were aware, but gave it no credence.

"For several days past I have heard rumors that a mob was being raised to raid the jail," Sheriff George Mann told the paper at the time. "I gave the matter no particular thought at first, because I did not believe it possible to raise a crowd in St. Clair County to do any such thing."

About 1 a.m. that day, the crowd formed in town, broke into the jail, grabbed Martin and beat him. They took him to the Seventh Street Bridge, where he was lynched.

Mann told the newspaper he fired shots from his residence to try to disperse the crowd but it didn't work. He caught up with the mob and cut Martin down from the bridge.

The masked men who carried out the lynching were never charged.

The prosecutor blamed the lynching on weak laws. The Times Herald reported Prosecutor Merriam stated he was sure the farmer's wife was raped, but because her husband didn't want that known and only alleged attempted rape Martin was looking at most a 10-year prison term.

Merriam told the paper that if the husband had said it was rape, Martin would have been facing life in prison and the lynching wouldn't have happened.

A call to the Equal Justice Initiative was not immediately returned Monday.

“Our nation’s history of racial injustice casts a shadow across the American landscape,” EJI Director Bryan Stevenson is quoted as saying on the nonprofit's website. “This shadow cannot be lifted until we shine the light of truth on the destructive violence that shaped our nation, traumatized people of color, and compromised our commitment to the rule of law and to equal justice.”
